"Composite panel, especially for an inverted roof"

The invention relates to a composite panel, particularly for an inverted roof.

Terrace areas that can be walked on are reversed Roofs "designed in such a way that pavement slabs directly be laid on insulation boards. The disadvantage here is that all unevenness of the roof skin, caused by Overlaps or the like are transferred to the pavement slabs so that stumbling blocks arise. There a Drying out and diffusing out towards the top is difficult with such constructions a reduction in the insulation capacity of the insulation boards.

According to another known method, the pavement slabs are laid on more or less suitable spacers above an insulation layer. It is disadvantageous that the production of a flat surface often walk 1st very difficult and the distance

The fee schedule of the Deutidien PatentanwalUkammer applies for this. ■ Place of jurisdiction for performance and payment: Nuremberg. The long-distance communication does not have any redistributive effect

holder can be adjustable or laid individually must · Commercially available spacers for rocker plates are very time-consuming · With individual ones too small spacers squeeze, depending on the load, the intermediate parts into the dam material, which in turn results in an uneven surface that can be walked on.

The object of the invention is to create a composite panel that is simple to manufacture, can be laid easily and with which the disadvantages of known constructions are avoided «

According to the invention, this object is essentially achieved with a composite panel of the type explained at the beginning Solved by connecting a pathway plate with a plastic D & mm plate to form a relocatable unit is.

Composite panels according to the invention can, as known Pavement slabs in sand, gravel or gravel bed, possibly even in mortar. All bumps off The roof cladding and ceiling can be easily leveled out, as when laying conventional paving slabs will.

It is particularly advantageous if the pavement slab is offset on two sides with respect to the insulation board, in such a way that a stepped fold is formed on all sides. In this way it is achieved in an advantageous manner that there are no direct joints between the DKmmplatten There is a connection to the outside air.

It is also possible to add the insulation board fold.

The connection of the pavement board with the insulation board can advantageously be designed in a form-fitting manner. According to a preferred embodiment are Pavement slab and plastic insulation board glued together

According to an advantageous development of the invention, the pavement slab has pulls on its insulation slab » turned side ventilation ducts on · The type and shape of these ventilation ducts is arbitrary and can be viewed can be easily adapted to the respective circumstances.

It is particularly advantageous _A are arranged wtiin the supports only in the corner regions and bonded to the insulation board.

If the pavement slabs are subjected to higher loads, it is advantageous to place the supports along the outer edges to arrange the pavement slabs at intervals.

For particularly heavy loads, it is advantageous to arrange the supports in a grid.

Appropriately, the parts of the Danish slabs standing over the edges of the pavement slab are on top of it provided with a light bitumen coating. But it is also possible to use larger parts or the entire top

To cover the surface of the insulation board with the bitumen paint.

Further advantages and features of the invention will become explained in more detail with reference to the drawing, which schematically shows exemplary embodiments. It shows:

1 shows a first embodiment of a composite panel according to the invention,

Fig. 2 shows a bottom view of a pavement slab according to the invention, and

3 shows a further embodiment.

In the embodiment shown in Fig. 1, a pavement slab 1 is firmly connected to an insulating panel 2 to form a unit. The pavement slab is offset on two sides with respect to the insulation slab 2 in such a way that a stepped rabbet 3 ¹ , 3 ⁿ , 3 " ¹ , 3 ^IV is created.

In Fig. 1 it is indicated in striohliert that either the insulating board 2 alone or in addition is provided with a fold V, 4 ⁿ . The pavement slab 1 has (Fig. 2) four supports 6 which are provided in the corner areas. It is also possible, as indicated in FIG. 1, to provide supports T or 7 and 8 (FIG. 3) on the longitudinal and / or transverse edges of the pavement slab 1 at intervals.

The surface of the insulation panel 2 facing the pavement slab 1 has when it is extruded

733424620.1273

Poly-foam is a bituminous coating on, which preferably covers the surfaces protruding beyond the pavement slab 1.

The arrangement of the supports 6 and 6, 7 and 8 are between the underside of the pavement slab 1 and the top of the insulation board formed 2 channels that allow ventilation and diffusion allow moisture.

The size of the pavement slabs 1 depends on the dimensions der Dämmplatten 2. Oämmplatten available under the trade name Roofmate from DOW Foam sheets or the like can be used.

The bitumen coating 9 protects the insulation board from damage that may occur in the pavement slab joints could cause incoming UV rays.

But it is also possible to use insulation boards made of particle-foamed polystyrene foam with a higher density to use ο

In FIG. 2, a bottom view of a pavement slab 1 is shown, which is provided with supports 6 in its corner regions is provided.

In the embodiment shown in FIG. 3, additional edges are provided on both the longitudinal and transverse edges Supports 7, 8 are provided. Between the supports and the corner feet 6 are thus, for example crossing channels 5 formed, which are used for ventilation.
